Hey how many of you are running with no discs and no spark arrestor plate on your Pure Polaris pipe??? I just tested it out today on my bike. Took everything off of the pipe and just put the chrome colored end back on. It really seemed to pull a hell of alot more like this, but the popping in the top end seems worse. What do you guys think? Is it a good idea to run it like this? I have no concern with noise... I currently run K&N clamp on and a 170 main, needle bumped up one. Do I need to jet up?
